Drinking loads and loads of water can help remove all the toxicity from the body and prevent bloating. Drinking water makes sure one doesn’t get dehydrated as our body needs lots of fluids, especially during the menstrual cycle. The oestrogen level goes down during periods, making the body retain fluids, which in turn leads to severe cramps. To avoid this, drinking at least 10 cups of water can keep bloating, indigestion and gas away.
